FYI. Not everyone has a chronograph so I thought I would post this for persons who wonder what to put in their snubbies and its velocity. The other day I got out my Model 649 357 Mag.
2-1/8" barrel, and tested two loads I use for it. Measured 10' from the muzzle, 10 rounds average velocity.
357 Magnum 145 grain Silvertip average 1107 FPS. The
38 Spl.+P 135 grain Gold Dot average 871 FPS.
I use both. The Silvertip is my carry ammo in this gun, but my wife and I also both have 642s, so I keep reloads in the 38+P GD in the cars instead of 357 so I don't have to worry about which gun we are carrying, and so my wife isn't trying to put 357s in her 38. I find the 357 Silvertip VERY accurate and manageable in the 649 and my 686 Mountain Gun. The rated velocity of the Silvertp out of 4" barrel is 1290FPS, but I find the 1107FPS to be just right and controlable in the snub barrel with still very reliable expansion. Guys, I did take photos, but it's really hard to see a fast bullet.
